A static DHCP entry for a PPPoE customer

I am trying to assign IP addresses to PPPoE customer via local DHCP pool on my BRAS. But I want to one customer to get a fixed IP address everytime. I tried to fix the address on the basis of mac/client-identifier but in vain. Any one did something similar or any idea how to get this done?

My pertinent configs are as follows. I am able to get IP address from the second pool "naeem" and I was even able to assign a fixed IP using a similar configuration (using client-identifier) from the Ethernet (LAN) interface of the router but I guess the DHCP request is a bit different in this scenario.
